Data storage is essential for applications that monitor user progress as well as allow logins or perform any other crucial task. There are a variety of ways to store user data but the best choice depends on the kind of problem you’re trying to solve.
Local storage is great for keeping small amounts of information which don’t require instant sync, such as login and registration details for users. However, it is restricted by the size of the device’s hard drive and is only accessible via client-side code (and cannot be manipulated through server-side scripts). Local storage is also vulnerable to lose data when an application is deleted, or if the device is reset.
The database storage is ideal for storing large amounts data which may need to edited. It enables you to keep records of the data of your users by keeping their unique identifiers in a table in your database and then reference that identifier every time you access the database. This is more complicated than other options for data storage however, it can be a good fit for large or enterprise apps which require storing information from multiple sessions.
WebView2 utilizes UDFs to store information about the browser, including cookies, permissions, and cached resources. The data expires according to the user’s Web & App Activity settings. It’s also possible to be manually cleared by the user through actions on Google. To store additional data about the user you must define the user’s personal UDF location that has Write access to the WebView2. See the WinUI 3.cs file in the WebView2Samples repo for an http://virtuadata.net/how-to-select-optimal-data-room-due-diligence-pricing-plan/ example of how to do this with ICoreWebView2Environment7.
